Detection of Turkey, Duck, and guinea fowl egg in hen egg products by species-specific PCR
Résumé
A simplex polymerase chain reaction (PCR) has been applied for the specific detection of hen, duck, turkey, and guinea fowl in egg products using species-specific primers targeting the mitochondrial cytochrome b genes. The species-specific PCR yielded excellent results for identification of duck, turkey, and guinea fowl eggs in hen egg products, since the detection of 0.1% of each species was achieved, in liquid egg products as well as in powders. The proposed method is then a potentially reliable and suitable technique in routine food analysis for the research of fraudulent species mixture practices.
